Coverity reports a resource leak for sysboot_filename which is allocated
by qemu_find_file.

In addition, that name is used to get the size of the image, but a

rcu: do not create thread in pthread_atfork callback

If QEMU forks after the CPU threads have been created, qemu_mutex_lock_iothread
will not be able to do qemu_cpu_kick_thread.  There is no solution other than
assuming that forks after the CPU threads have been created will end up in an
exec.  Forks before the CPU threads have been created (such as -daemonize)
have to call rcu_after_fork manually.

Notably, the oxygen theme for GTK+ forks and shows a "No such process" error
without this patch.

This patch can be reverted once the iothread loses the "kick the TCG thread"
magic.

User-mode emulation does not use the iothread, so it can also call
rcu_after_fork.

virtio-net: validate backend queue numbers against bus limitation

We don't validate the backend queue numbers against bus limitation,
this will easily crash qemu if it exceeds the limitation which will
hit the abort() in virtio_del_queue(). An example is trying to
starting a virtio-net device with 256 queues. E.g:

./qemu-system-x86_64 -netdev tap,id=hn0,queues=256 -device
virtio-net-pci,netdev=hn0

Fixing this by doing the validation and fail early.

virtio-serial: fix virtio config size

commit 9b70c1790acacae54d559d38ca69186a85040bb8
    virtio-serial: switch to standard-headers

changes virtio_console_config size from 8 to 12 bytes:
it adds an optional 4 byte emerg_wr field.

As this crosses a power of two boundary, this changes the PCI BAR size,
which breaks migration compatibility with old qemu machine types.
It's probably a problem for other transports as well.

As a temporary fix, as we don't yet support this new field anyway,
simply make the config size smaller at init time.

Long terms we probably want something along the lines
of virtio_net_set_config_size.

David Gibson [Mon, 23 Mar 2015 01:51:48 +0000 (12:51 +1100)]
i6300esb: Fix signed integer overflow

If the guest programs a sufficiently large timeout value an integer
overflow can occur in i6300esb_restart_timer().  e.g. if the maximum
possible timer preload value of 0xfffff is programmed then we end up with
the calculation:

timeout = get_ticks_per_sec() * (0xfffff << 15) / 33000000;

get_ticks_per_sec() returns 1000000000 (10^9) giving:

     10^9 * (0xfffff * 2^15) == 0x1dcd632329b000000 (65 bits)

Obviously the division by 33MHz brings it back under 64-bits, but the
overflow has already occurred.

Since signed integer overflow has undefined behaviour in C, in theory this
could be arbitrarily bad.  In practice, the overflowed value wraps around
to something negative, causing the watchdog to immediately expire, killing
the guest, which is still fairly bad.

The bug can be triggered by running a Linux guest, loading the i6300esb
driver with parameter "heartbeat=2046" and opening /dev/watchdog.  The
watchdog will trigger as soon as the device is opened.

This patch corrects the problem by using muldiv64(), which effectively
allows a 128-bit intermediate value between the multiplication and
division.

queue_signal() may call force_sig(), or return after kill pid (or queue
signal). If could return from queue_signal(), stop_all_task() would not
be called in time, the next end_exclusive() would be issue.

So in arm_kernel_cmpxchg64_helper() for ARM, need remove end_exclusive()
after queue_signal(). The related commit: "97cc756 linux-user: Implement

numa: Print warning if no node is assigned to a CPU

We need all possible CPUs (including hotplug ones) to be present in the
SRAT when QEMU starts. QEMU already does that correctly today, the only
problem is that when a CPU is omitted from the NUMA configuration, it is
silently assigned to node 0.

Check if all CPUs up to max_cpus are present in the NUMA configuration
and warn about missing CPUs.

Make it just a warning, to allow management software to be updated if
necessary. In the future we may make it a fatal error instead.

Command-line examples:

* Correct, no warning:

  $ qemu-system-x86_64 -smp 2,maxcpus=4
  $ qemu-system-x86_64 -smp 2,maxcpus=4 -numa node,cpus=0-3

9 years agopc: fix default VCPU to NUMA node mapping
Igor Mammedov [Thu, 19 Mar 2015 17:09:22 +0000 (17:09 +0000)]
pc: fix default VCPU to NUMA node mapping

Since commit
   dd0247e0 pc: acpi: mark all possible CPUs as enabled in SRAT
Linux kernel actually tries to use CPU to Node mapping from
QEMU provided SRAT table instead of discarding it, and that
in some cases breaks build_sched_domains() which expects
sane mapping where cores/threads belonging to the same socket
are on the same NUMA node.

With current default round-robin mapping of VCPUs to nodes
guest ends-up with cores/threads belonging to the same socket
being on different NUMA nodes.

For example with following CLI:

   qemu-system-x86_64 -m 4G \
         -cpu Opteron_G3,vendor=AuthenticAMD \
         -smp 5,sockets=1,cores=4,threads=1,maxcpus=8 \
         -numa node,nodeid=0 -numa node,nodeid=1

2.6.32 based kernels will hang on boot due to incorrectly built
sched_group-s list in update_sd_lb_stats()

Replacing default mapping with a manual, where VCPUs belonging to
the same socket are on the same NUMA node, fixes the issue for
guests which can't handle nonsense topology i.e. changing CLI to:
  -numa node,nodeid=0,cpus=0-3 -numa node,nodeid=1,cpus=4-7

So instead of simply scattering VCPUs around nodes, provide
callback to map the same socket VCPUs to the same NUMA node,
which is what guests would expect from a sane hardware/BIOS.
